The use of frequency conversion energy saving technology, is the use of power semiconductor devices, through intelligent control, can realize energy saving, in the Roots fan to take the frequency conversion of energy saving, because the wind volume of the Roots fan and the fan speed is proportional to the speed of the fan, so the use of frequency conversion energy-saving way, can reduce the power consumption of the fan, the traditional fan of the Roots fan is mainly to take the control of the wind volume of the control of the way to control the output flow. Therefore, the use of frequency conversion technology can reduce the operating speed of the Roots fan, thereby reducing electricity, the use of energy-saving technology for Roots fan, can realize the system soft start, soft stop, so that the operation of the Roots fan is more stable, thereby reducing mechanical wear and prolonging the service life of the Roots fan as well as the motor, but also the frequency conversion technology can realize fully automatic control, intelligent control.
Roots fan frequency conversion transformation is the main technology of the current energy saving Roots fan, according to the load characteristics of the Roots fan, the use of frequency converter for frequency control of the Roots fan, and artificially given signals for the frequency, under the condition of ensuring the production, to achieve frequency conversion and energy saving, through the frequency conversion transformation, can enhance the energy-saving efficiency, reduce the cost of maintenance and save labor.
